Hi! Thanks for playing! We're glad you enjoyed it. We haven't been able to actually fiddle with the itch.io page so we haven't been able to notify people of the bug. We didn't have enough time to actually fix it, so in case you get softlocked we have a tiny workaround, where you can press enter and you can go up to the next floor. It is not ideal but at least this way you can still enjoy most of the content.
Happy gaming!
